I discovered this image of Reza Shah The Great(he does look more ominous in this one that normal due to the quality) from some archived reverse image search leading to a now-deleted twitter post, and cannot find this image anywhere else, nor find any context of it.
Could anyone help me find the source or context of this image?
I believe the person standing behind him is his son, Mohammad Reza Pahlavi.
I'm not entirely sure but I was looking more into other images, and while Reza Shah is wearing a different uniform in this next image, if you look at the right-most person, it appears to be the same background person in the previous image(again I think it's Mohammad Reza Pahlavi), same suit, same haircut. This was their visit to Turkey (do not remember the year).

Thank you for any help!
